Sil'dihn Subterrane

variantEndwalker

Overview

An extensive warren of tunnels and waterways stretches beneath the barren lands of Thanalan, but none come now to marvel at this remnant of fallen Sil'dih. Its memories lie undisturbed, festering silently in the dark and the damp. Yet not for much longer. You have come at the personal behest of Nanamo Ul Namo, and together will you throw open the gate to the desert nation's troubled past.

Boss Encounters

Geryon the Steer

Colossal Strike: Tankbuster.
Exploding Catapult: Light damage to the entire party and summons several explosive barrels with either a red "burst" design on its top, or a blue "ring" design. The red-topped barrels explode in a large circle around them, while the blue-topped ones explode in a large ring around them.
Colossal Slam: Cone attack in the direction of a random player.
Subterranean Shudder: Has various effects depending on which path the party has taken and what decision was made before encountering Geryon.
Left Path: There will be four drains on both the east and west sides of the arena. The choice of whether or not to clear the pipes affects the attack.
Cleared Drain: One of the drains will light up cyan, causing water to spill out and knock back players from its location.
Clogged Drain: Two to four of the drains will light up red, causing mud to spill out and form damaging puddles on the ground for a short duration.
Center Path: The direction the Bulkhead Handle is turned determines the effect of the attack.
Turn Left: To the east and west of the arena are vents with fans. One set will begin to spin, indicating that players will be dragged across the arena toward that side.
Turn Right: To the east and west of the arena are platforms. Boulders will be carried onto them, then roll across the arena in a straight line during the next Exploding Catapult cast, dealing massive damage to players they crush.
Right Path: Mechanic is based on what fluid bursts from the pipe prior to the boss and is completely random.
Water: Two opposite quadrants of the arena churn, followed by the other two. The quadrants explode for damage in the order they began churning.

Soapy Sidekick: Silkie

Total Wash: Unavoidable roomwide AoE that deals high damage.
Squeaky Right/Left: The boss will attack the arena twice in a conal AoE in front of it, followed by an attack that hits two thirds of the arena based on the side of the arena indicated by the attack, with a safe zone in the opposite third of the arena.
Chilling Suds: The boss coats its tail in ice and fires four line AoEs in a cross pattern after casting Soap's Up.
Bracing Suds: The boss coats its tail in wind and fires an arena wide AoE with a safe zone within its hitbox after casting Soap's Up.
Soap's Up: Fires an attack pattern based on the prior Suds spell.
Slippery Soap: The boss will slide in a short AoE and immediately fire whichever Suds spell was previously stocked.
Spot Remover: The boss summons several water puddles around the arena that inflict a heavy Dropsy debuff if the player enters them.
Dust Bluster: The boss fires a large knockback from the center of the arena that will push players to the edge of the arena.
Fresh Puff: The boss summons three non targetable "Puffs" around the arena and inflicts them with Chilling Suds.
Soaping Spree: The Puffs and the boss fire the Chilling Suds pattern from their hitboxes, creating small safe zones around the arena.
Carpet Beater: A high damage tankbuster that hits the player with the highest enmity.
Eastern Ewers: Several large Ewers appear on the edge of the arena and fire water cannons while slowly moving from one edge of the arena to the other, dealing high damage if they come in contact with a player.

Lifeless Legacy: Gladiator of Sil'dih

Flash of Steel: Unavoidable heavy damage roomwide AoE.
Ring of Might: The boss will move to the center of the arena. A gauge will appear over its head, with three circles on the floor. The gauge above the boss will fill to one of three lines with a color corresponding to one of the circles on the floor. Once the cast finishes, the boss will fire an AoE in accordance with how full the gauge was. Shortly after, the remaining arena will be hit by a second AoE.
Sculptor's Passion: The boss will face a player and fire an untelegraphed, high damage line AoE.
Rush of Might: The boss will move to a corner of the room, charging the same gauge from Ring of Might, charging forward to the corresponding line and firing an AoE that fills the arena, before turning around and firing a second AoE behind it.
Wrath of Ruin: Several orbs are summoned to each edge of the arena, firing line AoEs in sets of two, creating several small safe zones across the arena.
Sundered Remains: An AoE is dropped in the center of the arena, followed by several AoEs in a clockwise pattern, filling the arena. After a short delay, the AoEs will detonate in the order they appeared in, starting with the center.
Mighty Smite: Heavy damage tankbuster that targets the player with the highest enmity.
Landing/Shattering Steel: Four proximity markers are placed at the corners of the arena, with large boulders landing on the markers. three of the four boulders will be cracked, and will shatter when the boss casts Shattering Steel, leaving the player behind them unprotected. Players must stand behind the uncracked boulder to break the boss's line of sight, then move away from the boulder after the attack, as it will explode.
Biting Wind/Shattering Steel: four air vents open on the floor of the arena, with one firing a large green arrow into the sky. When the boss begins casting Shattering Steel, players must step onto the vent with the arrow to be launched into the air, taking light damage with good timing, in order to receive the Liftoff buff and have it last long enough to avoid the boss's attack.
Hateful Visage: Two statues are summoned to two corners of the arena, and fire large line AoEs across the arena. the statues will then both rotate either clockwise or counterclockwise roughly thirty degrees and fire again. This attack will repeat three times until the statues have rotated a full ninety degrees.
Hateful Visage: The boss summons several two-faced statues around the arena, with one face of each statue firing an AoE that fills a quarter of the arena. Players must locate the area of the arena where none of the faces are firing an AoE to avoid damage.

Undead Shadowcaster: Zeless Gah

Show of Strength: Unavoidable roomwide AoE that deals high damage and activates the fire border around the edge of the arena.
Infern Gale: One of the scepters around the arena fires a large knockback.
Firesteel Fracture: A high damage tankbuster that targets the player with the highest enmity.
Infern Ward: four scepters appear and fire a persistent line AoE that knock the player back slightly and inflict a Stun debuff if the player touches them.
Infern Brand: The boss summons several fire orbs around the arena that explode after a short delay, creating small safe zones around the arena.
Cast Shadow: The boss fires two sets of four line AoEs with a short delay between each set, dealing high damage if the player is hit.
Cryptic Portal: The boss will place a portal underneath a fire orb, which is tethered to a portal. After a short cast the orb is moved to the portal. There is a second variation where the portal is swung to the other side of the fire orb then warped. Players touching these portals will also be warped.
Pure Fire: A large AoE is summoned under a player and explodes shortly after.
The boss will cast both Infern Gale and the fire orb version of Infern Brand.
Infern Brand: The fire orbs are replaced with large fire panels that grow after a short time fire large line AoEs across the arena. The boss will also not cast Infern Gale or Infern Well.
Infern Well: One of the scepters fire a pull in marker, then fires a large point-blank AoE, dealing high damage if players are pulled into it.

Armed Automaton: Thorne Knight

Spring to Life: The boss tethers to the cannons on one side of the arena, and the mammets on another. After a short cast, both will fire line AoEs across the arena, creating safe zones.
Blistering Blow: High damage tankbuster that targets the player with the highest enmity.
Fore Honor: The boss fires a forward facing untelegraphed AoE that deals high damage.
Slashburn: The boss fires a large red fire line AoE and two massive blue fire cone AoEs, each in a different direction. There is a variant of this attack that tethers the swords together, and switches the location of the AoEs, requiring players to move to the correct safe zone in anticipation of the swap. This can be dodged easily by standing on the midline of the red portion of the attack, as you will then be standing between the blue AoEs once the positions swap.
Signal Flare: The boss drops three sets of lines of large AoEs across the arena that will detonate after the arena is filled in the order they appeared.
Blaze of Glory: Two large fire orbs are summoned to the arena that fire large line AoEs in a cross pattern. This is paired with either Spring to Life or Slashburn.
